2.4.3 Test probe
After connecting a probe to the probe connector, a self-test is automatically started. The
digital part, the analog part and the measuring sensors of the probe are checked for
correct function. If a fault is detected that could affect the measurement, a corresponding
message is displayed and measurements are not possible.
Probe is not working properly
Due to a defective probe, any high radiation levels that may be present cannot be de-
tected.
⇒
Observe the information displayed during and after the self-test of a probe. If there
is any doubt about the correct functioning of the probe, a suitable test source can
be helpful to check the probe.
⇒
In order to make the correct probe selection, you should always obtain knowledge
of the expected frequency and field strength before starting a measurement
2.5 Initial commissioning
2.5.1 Switch on the device
Damage to a device covered in dew during commissioning
A device stored or transported at low temperatures may become covered in dew when
brought into a warm room. If it is put into operation in this condition, it may be dam-
aged.
⇒
To prevent damage, wait until all dew on the surface of the device has evaporated.
⇒
The device is not ready for operation until it has reached the operating range of ‒20
to +50 °C.
